High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

A. Mapping on the proposed scale based on the aerial photographs or high
resolution remote sensing data, GPS, ground survey or in combination.
B. The details in the maps to be given like road/railways, rivers, administrative
boundaries from villages to state, infrastructures like bridges, power stations,
hospitals, shelters, helipads, dropping points, basic land use like water bodies,
settlements, built up areas, arable lands, forests, communication lines etc.
C. The policy and identification of the districts among the 241 multi-disaster prone or
major disaster prone districts are to be given.
D. Estimate the cost of preparation of the districts among 241 multi-disaster prone
or major disaster prone districts are to be given.
NTDB ON 1:10,000 SCALE- A NATIONAL NEED
As pointed out in Para 1 of this chapter, the SOI is in possession of the NTDB on
1: 50,000 scale. Admittedly, scales do not have as much relevance in digital
environment as for paper maps; but the NTDB of SOI has been made by digitization of
analogue maps. The NTDB have not been captured in digital mode with the result that
this NTDB even while being in digital environment suffers from plotting error. Even
assuming zero plotting error, the NTDB can’t support the kind of details as required by
the present map users. The detailed features call for higher scale maps even when
available in digital form. For instance, on 1:50,000 scale, it is not possible to depict utility
buildings like hospitals, schools, police stations, post offices etc, whereas these have
become indispensable to be shown in village maps. On 1:10,000 scales, all these
